Re: Mark's 1G Winter Projects
 

Are you going to paint the interior? Could look bad ass if the color of your cage matched the wheels and the rest of the inside matched the color of the car.

Re: Mark's 1G Winter Projects
 

I wouldn't mind a nice finish like that! I plan on painting the inside & cage.

Re: Mark's 1G Winter Projects
 

I went and checked out the rouge fabrication website and wow those are some nice notchers for sure and lots of other cool goodies. Must need at least 100' or so of 4130 for the new cage huh? I like the 2.0 long rod idea, so many different ways you can build these motors it's hard to decide the perfect setup. What were your reving in the 2.2 Vs your goal in the 2.0? Boost goal? Pretty awesome as always, gonna be fun to watch you chase a 7, keep up with the updates!

Re: Mark's 1G Winter Projects
 

Yeah, I've just placed the order for the 4130, MAP helped me source materials. So 3 different sizes of tube and 100ft total, good guess! I should have the main hoop bent and installed over the Thanksgiving weekend. I reved my 2.2 to just over 9k. I'm planning on running the 2.0LR to a bit over 10k, and continually increasing the Boost. I was running around 50psi with the last turbo, but with a new head gasket set up I'm going to target a lot more. Thanks for the support, forums are losing attention, but they're way better than other digital media formats. The car, tune, and my driving are a long way away from sevens but there's nothing wrong with chasing them!

Re: Mark's 1G Winter Projects
 

I've been getting a lot accomplished lately. I found more weight to shave off, I weighed everyghing out and negated the 2g carbonfiber dash & dash bar weigh. 50 lbs came out that will not be added back in! This will help offset the weight im adding due to the 25.5 cage.

I also started the cage work over the thanksgiving weekend, I'm super happy how it's all turning out! The cage fitment is 100x better than my prebent sw cage!

The rouge fabrication tube notcher is awesome too! Every joint is very tight, makes for easy and beautiful welds.

Next up is to finish the floor north south bars and the front floor bar. It's all coming together!

Re: Mark's 1G Winter Projects
 

I was pretty proud of my cage fitment tell I saw this. You are an artist sir! The pillar bars are very impressive probably best I have seen in a 1g. I really never thought about how much of the inner skin Panels a guy can cut out. That perfect notch is gonna make the welding a little better time for sure. Easier to focus on making the welds as perfect as possible! Do you weld your chromoly with red tungsten? Well done as always, keep it up

Re: Mark's 1G Winter Projects
 

I love it! That cage looks like it fits so well! And those joints are as close as you can get, you knocked this out of the park so far!

Re: Mark's 1G Winter Projects
 

Reminds me of when Brent was gutting his wife's car way back when. He ended up with almost no internal structure and I think he even replaced almost the entire floor with sheetmetal. He was down around 2100 lbs as AWD IIRC. That car was so light.

Looks good! 1G love!

Re: Mark's 1G Winter Projects
 

Thanks! My old cage fitment and my tig welding capability was at a beginner level. Now that I have 10 years on tig welding experience, I wanted to make sure I could be proud of this cage.

It has not been easy. The design of the cage, assembly steps, and being able to weld it has been a challenge, due to being so close to the car.

I planned ahead to use a micro torch when i made the fitment so close.

Thanks! I'm excited too see your project!

I was able to take the floor bars out to finish weld them.

Re: Mark's 1G Winter Projects
 

I have never seen a micro torch before but damn that is cool! There is so many tools that exist to make things easier. I am a little suprised you are still manually making these bends or I am at least assuming from the pics. I have seen some people have been able to mod hydraulic cylinders on your style bender before. Those floor bars are super impressive and super convenient they popped out to weld most of that up. Everything seems so tight it doesn't even look like you will have room to weld all the way around!

Re: Mark's 1G Winter Projects
 

^Agreed.
I just want to watch all this in action

Re: Mark's 1G Winter Projects
 

Loving the progress, great fitment so far!!

Re: Mark's 1G Winter Projects
 

thanks for the feedback guys!

At this point the cage is close to being done. I just need to get the front of the funny car cage bent and welded in. I need to buy a new 1.5" bending die for this, so i need to wait a week or two until the die shows up. I also need to figure out a custom window net setup, mount the seat, and fabricate mounts for the steering column. My goal is to have it certified this month!

My chassis fabrication confidence has grown and this has been an awesome project so far!

It's a shame I'm going to paint the cage, not all of the welds are this clean, but the majority are good like this.

Re: Mark's 1G Winter Projects
 

i feel safe just looking at it.

Re: Mark's 1G Winter Projects
 

That's turned out awesome so far!

Re: Mark's 1G Winter Projects
 

Thanks guys, I'm super pumped for next year.

This was a good weekend of progress. I ordered a custom Stroud window net. They produced it in 24 hrs from my order! It fits awesome. I also reduced the size off rod used to mount the net to shave off some weight.

http://i412.photobucket.com/albums/p...216_084744.jpg

Everything I do I question if I can cut weighty in the process. I also ordered a new polycarbonate formed windshield from optic armor, this will shave off some good weight too!

I made a new steering column, to reduce weight and stiffen up what I had for a solution before. I machined aluminum inserts to adapt to roller bearings. The tube is 4130 1.5" x 0.035", and the shaft is 4130 3/4" x 0.049". Turned out nice.

Re: Mark's 1G Winter Projects
 

Those door panel "scuff plates" or whatever they're called gotta be worth a few ounces :P are you going to run interior panels or shell the doors?

Re: Mark's 1G Winter Projects
 

Oh snap you're killing me!

I have a bead roller so I'm considering making thin aluminum door panels. Once I receive the carbon fiber Kevlar reinforced doors I'll figure out what to do to finish them off.

Re: Mark's 1G Winter Projects
 

Free weight savings is the best kind!

Re: Mark's 1G Winter Projects
 

The cage is done! I'll be getting it certified next month. It's been an awesome project. The seat mount and belts are done too.

I also removed a little more than 10 more pounds of metal from the front driveshaft carrier bearing mount and supporting structure from driveshaft tunnel. This sucked to remove, i was drilling spotwelds for 3 to 4 hours! It was well worth that time for that much of a weight reduction. I'll need to get this thing on corner scales to see what it comes out at.

http://i412.photobucket.com/albums/p...227_080419.jpg

To remove the driveshaft support structure I had to cut out emergency brake cable bulkhead from the floor. I got to use my bead roller and made a patch panel, and plug weld at all the areas where I accidentally drilled through while removing the spot welds. I also stitch welded back in the floor section I cut for the tube that intersects it.
